had a trip to msl monday had a new cooler pump and 77mm pulley but could not get a proper dyno reading due to belt slip so advice from acid ive ordered a gates belt.
but i am running standard exhaust the power delivery from the tune and pulley even with a slippy belt is so much more responsive
But i have seen some of you guys with a cat delete and resonator delete no pulley make great figures
i would like to hear your views and or experiances with exhaust mods etc
thanks

Imran at MSL did both my previous E55 (secondary cats & x -pipe) and my current E63 Biturbo resonator.
Well worth doing, but no idea on if there much in the way of power gains from the exhaust work alone.
It's worth doing just to hear more volume when accelerating although I gather its much louder outside the car.

I think the E55 was around £400 and the E63 around £300 (less work to do) but give Imran a call for his latest prices.
Mine were done long ago in 2014 and 2019.
